Compared with other compounds in its class, the molecular weight of 129.18 g/mol gives 3-Methyl-5-(methylthio)-1H-1,2,4-triazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Methyl-5-(methylthio)-1H-1,2,4-triazole (CAS 34985-98-3), a certified reference material (molecular formula C4H7N3S, MW 129.18 g/mol) for analytical method development and quality control.
The molecular framework of 3-Methyl-5-(methylthio)-1H-1,2,4-triazole (C4H7N3S) is characterized by a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
